A reflector assembly for use with a paraboidal reflector comprises a generally-cylindrical body (302) having a plurality of stepped facets (306) extending circumferentially around its internal surface. Each facet serves to reflect divergent light from a light source (308) back onto the primary reflector (314) for re-reflection thereby enhancing the beam produced. Such a reflector can be used with existing lamps or alternatively a purpose built composite reflector incorporating such an element can be designed.
